How To Distinguish Different Laser Machine?
Jul 10, 2018

The distinction between fiber laser marking machines, how to distinguish all kinds of fiber laser marking machines, MRJ will introduce to you.

1, the laser wavelength is different

Deep UV laser marking machine: 266 nm

Green laser marking machine: 532nm

Light pump YAG laser marking machine: 1064nm

Semiconductor side pump YAG laser marking machine, semiconductor end pump YAG laser marking machine: 1064nm

Fiber laser marking machine: 1064nm

CO2 laser marking machine: 10.64um

2, the working principle is different

Lamp-pumped YAG laser marking machine: Xenon lamp is used as the energy source (excitation source), ND: YAG is used as the medium for generating laser light. The specific wavelength can be used to promote the production level transition of the working substance to release the laser, and the laser energy is amplified. A laser beam is formed that is processed into the material.

CO2 laser marking machine: CO2 gas is used to charge the discharge tube as the medium for generating laser light. When a high voltage is applied to the electrode and a glow discharge is generated in the discharge tube, the gas molecules can release the laser light and amplify the laser energy. A laser beam is formed that is processed into the material.

Semiconductor side pump YAG laser marking machine: using a 808nm semiconductor laser diode to pump Nd: YAG medium, the medium generates a large number of inverted particles to form a giant pulse laser output with a wavelength of 1064nm under the action of Q switch, electro-optical conversion efficiency high.

Semiconductor end pump YAG laser marking machine: The semiconductor pump light (808 nm) is pumped directly from the end face of the laser crystal, and the laser is output through the optical lens group. The light conversion efficiency is greatly improved.

Fiber laser marking machine: direct output laser from fiber.

3, the scope of the mark and the price are different

CO2 laser marking machine: mainly used for non-metal (wood, acrylic, paper, leather, etc.), the price is cheap.

Green laser marking machine, UV laser marking machine: mainly used in high-end ultra-fine IC and other products. The price is higher and the product is customized.

Lamp pump YAG laser marking machine: mainly used for low-demand products such as metal and plastic. The laser marking machine is moderately priced.

Semiconductor side pump laser marking machine: It is the same as the lamp pump YAG laser marking machine, but it is stable and the price is moderate.

Semiconductor end pump laser marking machine: It is the same as the lamp pump YAG laser marking machine. It is stable and saves electricity, but it is used for high-end production and the price is high.

Fiber laser marking machine: fine marking, power saving, maintenance-free, for high-end products such as mobile phones and buttons. The price is high.

In short, these tips are very helpful for marking the fiber laser marking machine. Familiarity and mastery are necessary for the operating staff! I also hope that peer practitioners will see this and have some help.
